I'll be moderating a free webinar on Thursday called
Cluster 3.0: Dynamic Provisioning with MOAB and XCAT
where the idea of dynamic provisioning will be discussed.
i.e. booting nodes into different software environments
through the scheduler.
I find this processes interesting because rather
than running various environments on top of a virtual layer,
dynamic provisioning can boot what ever you want on
the nodes -- when the node is allocated to your job.
